i d e. Simile? omie. or ex Le weites container or reservoir 18 located in the lower portion and, one corner of the housing 1.

The opposite bore of the control cock 12 has a connection 19 directly connected to said reservoir or container 18 which may be which contains the air pump and compresv sor, is provided with a suitable driving gear 22 meshing with a pinion 23 of the motor 24 I by means of which said compressor and pumps are operated. The three-way or controlling cock 12 is provided with a stem 26 by means of which the same may be controlled and operated in order lto vapproximately evacuate the congealing chambers 4. The chambers 4 are each provided with a hollow cap 28 provided with a gasket 29 arranged to tightly engage the upper surf face of the cover 6 of the container 3 and also the tops of said tubular chambers 4.

The aperture of the cover 6 through which .the chambers 4 are suspended are provided with diametrically opposed slots 31 by means of which said slots the removal of said chambers 4 may be facilitated.

The caps 28 may be rigidly retainedv against the cover 6 by any suitable locking mechanism, a portion of which is disclosed as at 23 in Figs. 2 and 3 of the drawings.

An ammonia or other suitable refrigerant intake valve 36 provides a means whereby any suitable refrigerant, preferably ammonia', may by means of the ammonia compressor 'within the housing 16, be int'roduced in the direction vindicated by the arrows through the connections 37, provided with a suitable gage 39, to the ammonia coil 41 within a suitable condenser 42 which is also provided with a connection 47 to a standard eapansion valve 48 whereby the refrigerant may be conducted by means of a suitable'connection 49 and slip-joint 51,

.to the circulating coil 52 within the container 3, then through the slip-joint 53 Ato the valve 54 and back to the compressor within the housing 16.

rlfhe operation is as follows:

Water to be Yfrozen is first introduced by means of a connection or pipe 21 from any suitable source to the container 18.l

By means of the motor 24, pinion 23 thereof, and gear 22, the pump and compressor within the housing 16 are operated. An extension, not. shown, engages the stem 26 of the three-way cock or controlling Valve 12 and turns the same so that the interior ci' Lbe congealing chambers '4 are connected natation.l

with the air pump as the said chambers are hermetically sealed by means of the hollow caps and gaskets 28 and 29 respectively.

Itis evident that the atmospheric pres,- su're within said chambers 4 will be rapidly reduced by means of the suction of the pump within the housing 16. A vacuum will be formed within said chambers 4 which vacuum or reduction of pressure will tend to facilitate the lowering of thetemperature within the said chambers 4 and thereby assist the cooling agent circulating through the ammonia coils 52. The container 3 may or may not \be filled with a suitable conductor, such' as brine or the like.4

An ammonia compressor within the housing 16 assists in lowering the temperature within the chambers 4 in the following manner: Ammonia is pumped through'the connection 37 in the direction indicated by the arrows throughout the several views at a pressurethat will cause the same to condense to liquid form in the lower portion of a coil 41 within the condenser 2 where the heat due to compression will be partially removed by means of the water {lowing through a supply'43 and'through an overflow 44 thereof. As the heat of compression is removed the .cooling agent or ammonia, in the form of a liquid, is carried from 'the coil 41 by-means of a suitable connection 47 to a standard expansion valve 48 whereby the pressure and the temperature is rapidly reduced to such an extent that the connection 49, beyond said valve 48, is filled with a liquid spray which forms an effective cooling agent which will be eX` pended through the lslip-joint 51 and coil 52 thereby effectively cooling the interior of the container 3 and the congealing chambers 4- suspended therein. This liquid spray is evaporated into gas by the heat from the water being'frozen. The gas is returned by means of a slip-joint 53 and valve 54 .to

the ammonia compressor within the housing 16.

It is obvious from the foregoing that following a well known principle or law of physics that the reduction of atmospheric pressure reduces the volume of air fand thereby said temperature may be effectively cooled at a greatly reduced vinciting capacity. Therefore it is evident that the vacuum produced in the cooling chambers 4 by means of the pump Within the housing 16 through the connections 9, 14, and the three-way cock 12 will tend to facilitate a rapid lowering or reduction in the temperature. of said i congealing chambers 4.

rl`he vacuum within said chambers 4 will also tend to spray water onto the cooled walls ofthe Vtubular cooling chambers 4 and thereby produce a substantially tubular block of ice inthe following manner z,
